KAELUS IPA-1921A Dual Band PCS/AWS Passive Intermodulation (PIM) analyzer

The Kaelus iPA-1921A Passive Intermodulation (PIM) analyzer is the first battery powered PIM Test Analyzer versatile enough to support multiple test scenarios such as testing at the top of the tower, base of tower, roof top and in-building for DAS systems. This IEC compliant 20W, rugged, battery operated design can be operated via remote control with any WiFi enabled phone, tablet or laptop computer. This allows hands-free dynamic testing that is safe and convenient. Add the optional Range to Fault (RTF) module to quickly identify the location of PIM and Return Loss sources. An intuitive touch screen interface is also available for local control, performing tests and quickly generating site reports.

ATM
Asynchronous Transfer Mode (ATM) is a switching technique for telecommunication networks. It uses asynchronous time-division multiplexing, and it encodes data into small, fixed-sized cells. This differs from networks such as the Internet or Ethernet LANs that use variable sized packets or frames.

Linearity
Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Return Loss (RL)
Return Loss (RL) is the ratio of the incident power to the reflected power expressed in dB. RL = 10log (Pin/Pback)
